This application claims priority from Japanese Application No. 2012-068163, filed on Mar. 23, 2012, the content of which is incorporated by reference herein in its entirety.
BACKGROUND
1. Technical Field
The present application relates to a device, a method, and a storage medium storing therein a program. More particularly, the present application relates to a device including a touch screen, a method of controlling the device, and a storage medium storing therein a program for controlling the device.
2. Description of the Related Art
A touch screen device having a touch screen has been known. Examples of the touch screen devices include, but are not limited to, a smartphone and a tablet. The touch screen device detects a gesture of a finger, a pen, or a stylus pen through the touch screen. Then, the touch screen device operates according to the detected gesture. An example of the operation according to the detected gesture is described in, for example, International Publication Pamphlet No. 2008/086302.
The basic operation of the touch screen device is implemented by an operating system (OS) built into the device. Examples of the OS built into the touch screen device include, but are not limited to, Android, BlackBerry OS, iOS, Symbian OS, and Windows Phone.
Most of the touch screen devices display a screen called a home screen on a display. Objects called icons are disposed on the home screen. When detecting a gesture performed for an icon, the touch screen device executes an application corresponding to the icon for which the gesture is performed.
As the number of applications installed in the touch screen device increases, the number of icons disposed on the home screen increases, thus consuming a space of the home screen that is reserved for disposing icons. Therefore, there is a method of securing a space on the home screen by managing the icons disposed on the home screen in such a manner that the icons are contained in a folder in a certain unit. However, it is difficult for the user to know the number of icons contained in the folder. For example, when the number of icons containable in a folder is limited, the user, who fails to know the number of icons contained in the folder, is inconvenienced because the user cannot know whether an icon is containable in the folder.
For the foregoing reasons, there is a need for a device, a method, and a program that can comprehensibly display the status of a folder containing icons to a user.
SUMMARY
According to an aspect, a device includes a touch screen display and a controller. The touch screen display displays a folder for containing therein an icon corresponding to an application. The controller changes a display mode of the folder according to the number of icons contained in the folder.
According to another aspect, a method is for controlling a device including a touch screen display. The method includes: displaying a folder on the touch screen display, the folder being configured to contain therein an icon corresponding to an application; and changing a display mode of the folder according to the number of icons contained in the folder.
According to another aspect, a non-transitory storage medium stores a control program. When executed by a device including a touch screen display, the program causes the device to execute: displaying a folder on the touch screen display, the folder being configured to contain therein an icon corresponding to an application; and changing a display mode of the folder according to the number of icons contained in the folder.

In the example of FIG. 1, each of the display 2A and the touch screen 2B is approximately rectangular-shaped; however, the shapes of the display 2A and the touch screen 2B are not limited thereto. Each of the display 2A and the touch screen 2B may have any shape such as a square, a circle or the like. In the example of FIG. 1, the display 2A and the touch screen 2B are arranged in a superimposed manner; however, the manner in which the display 2A and the touch screen 2B are arranged is not limited thereto. The display 2A and the touch screen 2B may be arranged, for example, side by side or apart from each other. In the example of FIG. 1, longer sides of the display 2A are along with longer sides of the touch screen 2B respectively while shorter sides of the display 2A are along with shorter sides of the touch screen 2B respectively; however, the manner in which the display 2A and the touch screen 2B are superimposed is not limited thereto. In case the display 2A and the touch screen 2B are arranged in the superimposed manner, they can be arranged such that, for example, one or more sides of the display 2A are not along with any sides of the touch screen 2B.
The display 2A is provided with a display device such as a liquid crystal display (LCD), an organic electro-luminescence display (GELD), or an inorganic electro-luminescence display (IELD). The display 2A displays text, images, symbols, graphics, and the like.
The touch screen 2B detects a contact of a finger, a pen, a stylus pen, or the like on the touch screen 2B. The touch screen 2B can detect positions where a plurality of fingers, pens, stylus pens, or the like make contact with the touch screen 2B.
The detection method of the touch screen 2B may be any detection methods, including but not limited to, a capacitive type detection method, a resistive type detection method, a surface acoustic wave type (or ultrasonic type) detection method, an infrared type detection method, an electro magnetic induction type detection method, and a load sensing type detection method. In the description herein below, for the sake of simplicity, it is assumed that the user uses his/her finger(s) to make contact with the touch screen 2B in order to operate the smartphone 1.
The smartphone 1 determines a type of a gesture based on at least one of a contact detected by the touch screen 2B, a position where the contact is detected, a change of a position where the contact is detected, an interval between detected contacts, and the number of detection times of the contact. The gesture is an operation performed on the touch screen 2B. Examples of the gestures determined by the smartphone 1 include, but are not limited to, touch, long touch, release, swipe, tap, double tap, long tap, drag, flick, pinch in, and pinch out.
“Touch” is a gesture in which a finger makes contact with the touch screen 2B. The smartphone 1 determines a gesture in which the finger makes contact with the touch screen 2B as touch. “Long touch” is a gesture in which a finger makes contact with the touch screen 2B for longer than a given time. The smartphone 1 determines a gesture in which the finger makes contact with the touch screen 2B for longer than a given time as long touch.
“Release” is a gesture in which a finger separates from the touch screen 2B. The smartphone 1 determines a gesture in which the finger separates from the touch screen 2B as release. “Swipe” is a gesture in which a finger moves on the touch screen 2B with continuous contact thereon. The smartphone 1 determines a gesture in which the finger moves on the touch screen 2B with continuous contact thereon as swipe.
“Tap” is a gesture in which a touch is followed by a release. The smartphone 1 determines a gesture in which a touch is followed by a release as tap. “Double tap” is a gesture such that a gesture in which a touch is followed by a release is successively performed twice. The smartphone 1 determines a gesture such that a gesture in which a touch is followed by a release is successively performed twice as double tap.
“Long tap” is a gesture in which a long touch is followed by a release. The smartphone 1 determines a gesture in which a long touch is followed by a release as long tap. “Drag” is a gesture in which a swipe is performed from an area where a movable-object is displayed. The smartphone 1 determines a gesture in which a swipe is performed from an area where the movable-object displayed as drag.
“Flick” is a gesture in which a finger separates from the touch screen 2B while moving after making contact with the touch screen 2B. That is, “Flick” is a gesture in which a touch is followed by a release accompanied with a movement of the finger. The smartphone 1 determines a gesture in which the finger separates from the touch screen 2B while moving after making contact with the touch screen 2B as flick. The flick is performed, in many cases, with a finger moving along one direction. The flick includes “upward flick” in which the finger moves upward on the screen, “downward flick” in which the finger moves downward on the screen, “rightward flick” in which the finger moves rightward on the screen, and “leftward flick” in which the finger moves leftward on the screen, and the like. Movement of the finger during the flick is, in many cases, quicker than that of the finger during the swipe.
“Pinch in” is a gesture in which a swipe with a plurality of fingers is performed in a direction to move the fingers toward each other. The smartphone 1 determines a gesture in which the distance between a position of one finger and a position of another finger detected by the touch screen 2B becomes shorter as pinch in. “Pinch out” is a gesture in which a swipe with a plurality of fingers is performed in a direction to move the fingers away from each other. The smartphone 1 determines a gesture in which the distance between a position of one finger and a position of another finger detected by the touch screen 2B becomes longer as pinch out.
The smartphone 1 performs operations according to these gestures which are determined through the touch screen 2B. Therefore, user-friendly and intuitive operability is achieved. The operations performed by the smartphone 1 according to the determined gestures may be different depending on the screen displayed on the display 2A. In the following explanation, for the sake of simplicity of explanation, the fact that the touch screen detects the contact(s) and then the smartphone determines the type of the gesture as X based on the contact(s) may be simply described as “the smartphone detects X”, “the controller detects X”, “the touch screen detects X”, or “the touch screen display detects X”.
An example of the screen displayed on the display 2A will be explained below with reference to FIG. 4. FIG. 4 represents an example of a home screen. The home screen may also be called “desktop”, “standby screen”, “idle screen”, or “standard screen”. The home screen is displayed on the display 2A. The home screen is a screen allowing the user to select which one of applications (programs) installed in the smartphone 1 is executed. The smartphone 1 executes the application selected on the home screen in the foreground. The screen of the application executed in the foreground is displayed on the display 2A.
Icons can be arranged on the home screen of the smartphone 1. A plurality of icons 50 are arranged on a home screen 40 illustrated in FIG. 4. Each of the icons 50 is previously associated with an application installed in the smartphone 1. When detecting a gesture for an icon 50, the smartphone 1 executes the application associated with the icon 50 for which the gesture is detected. For example, when detecting a tap on an icon 50 associated with a mail application, the smartphone 1 executes the mail application. Folders for containing the icons can also be on the home screen of the smartphone 1.
The icons 50 include an image and a character string. The icons 50 may contain a symbol or a graphic instead of an image. The icons 50 do not have to include either one of the image and the character string. The icons 50 are arranged based on a layout pattern. A wall paper 41 is displayed behind the icons 50. The wall paper may sometimes be called “photo screen”, “back screen”, “idle image”, or “background image”. The smartphone 1 can use an arbitrary image as the wall paper 41. The smartphone 1 may be configured so that the user can select an image to be displayed as the wall paper 41.
The smartphone 1 can include a plurality of home screens. The smartphone 1 determines, for example, the number of home screens according to setting by the user. The smartphone 1 displays a selected one on the display 2A even if there is a plurality of home screens.
The smartphone 1 displays an indicator (a locator) 51 on the home screen. The indicator 51 includes one or more symbols. The number of the symbols is the same as that of the home screens. In the indicator 51, a symbol corresponding to a home screen that is currently displayed is displayed in a different manner from that of symbols corresponding to the other home screens.
The indicator 51 in an example illustrated in FIG. 4 includes four symbols. This means the number of home screens is four. According to the indicator 51 in the example illustrated in FIG. 4, the second symbol from the left is displayed in a different manner from that of the other symbols. This means that the second home screen from the left is currently displayed.
The smartphone 1 can change a home screen to be displayed on the display 2A. When a gesture is detected while displaying one of home screens, the smartphone 1 changes the home screen to be displayed on the display 2A to another one. For example, when detecting a rightward flick, the smartphone 1 changes the home screen to be displayed on the display 2A to a home screen on the left side. For example, when detecting a leftward flick, the smartphone 1 changes the home screen to be displayed on the display 2A to a home screen on the right side. The smartphone 1 changes the home screen to be displayed on the display 2A from a first home screen to a second home screen, when a gesture is detected while displaying the first home screen, such that the area of the first home screen displayed on the display 2A gradually becomes smaller and the area of the second home screen displayed gradually becomes larger. The smartphone 1 may switch the home screens such that the first home screen is instantly replaced by the second home screen.
An area 42 is provided along the top edge of the display 2A. Displayed on the area 42 are a remaining mark 43 indicating a remaining amount of a power supply and a radio-wave level mark 44 indicating an electric field strength of radio wave for communication. The smartphone 1 may display time, weather, an application during execution thereof, a type of communication system, a status of a phone call, a mode of the device, an event occurring in the device, and the like in the area 42. In this manner, the area 42 is used to inform the user of various notifications. The area 42 may be provided on any screen other than the home screen 40. A position where the area 42 is provided is not limited to the top edge of the display 2A.
The home screen 40 illustrated in FIG. 4 is only an example, and therefore the configuration of each of elements, the arrangement of the elements, the number of home screens 40, the way to perform each of operations on the home screen 40, and the like do not have to be like the above mentioned explanation.

In the example of FIG. 5, the smartphone 1 is provided with three types of sensors in order to detect its position and attitude; however, the smartphone 1 does not have to be provided with some of the sensors. Alternatively, the smartphone 1 may be provided with any other type of sensor for detecting at least one of the position and the attitude.
An example of control based on the function provided by the control program 9A will be described with reference to FIGS. 6 to 11. The function provided by the control program 9A includes a function for changing a display mode of a folder according to the number of icons contained in the folder. For example, based on the function provided by the control program 9A, the smartphone 1 changes a display mode of a folder to display the number of icons contained in the folder.
FIG. 6 represents an example of control for generating a folder according to an operation of the user, containing icons in the generated folder, and displaying the number of icons contained in the folder.
As illustrated in Step S11, for example, when an icon 50a is long-touched with a finger of the user, the smartphone 1 detects the same as a movement start operation for the icon 50a. After detecting the movement start operation, the smartphone 1 moves the icon 50a according to a drag of the icon 50a. The smartphone 1 may detects various operations detectable through the touch screen 2B, such as a double tap on the icon 50a and a long touch for the home screen 40, as the movement start operation.
Subsequently, as illustrated in Step S12, when the icon 50a is dragged by a finger of the user and is superimposed on an icon 50b, the smartphone 1 generates a folder 52 for containing the icon 50a and the icon 50b. 
Subsequently, as illustrated in Step S13, the smartphone 1 contains the icon 50a and the icon 50b in the generated folder 52 and disposes the folder 52, to which an image 53 corresponding to the number of contained icons is added, on the home screen 40. Herein, “the image 53 is added” means “the image 53 is disposed near” or “a portion or the whole of the image 53 is superimposedly disposed”. In this example, since two icons 50 are contained in the folder 52, a numeral “2” is included in the image 53.
By the control illustrated in FIG. 6, the number of icons contained in the folder 52 can be comprehensibly displayed to the user. Although FIG. 6 represents an example of generating a folder in response to the approach of icons therebetween, the operation for generating a folder is not limited thereto.
Although FIG. 6 represents an example of displaying the number of icons 50 contained in the folder, the smartphone 1 may also display the number of icons containable in the folder, that is, the number of icons 50 that can be additionally contained in the folder, in association with the icons 50. FIG. 7 represents an example of control for generating a folder according to an operation of the user, containing icons in the generated folder, and displaying the number of icons containable in the folder. In the following, a case where the number of icons containable in the folder is 12 will be described as an example.
As illustrated in Step S21, for example, when an icon 50a is long-touched with a finger of the user, the smartphone 1 detects the same as a movement start operation for the icon 50a. Subsequently, as illustrated in Step S22, when the icon 50a is dragged by a finger of the user and is superimposed on an icon 50b, the smartphone 1 generates a folder 52 for containing the icon 50a and the icon 50b. Subsequently, as illustrated in Step S23, the smartphone 1 contains the icon 50a and the icon 50b in the generated folder 52 and disposes the folder 52, to which an image 53 corresponding to the number of icons containable in the folder 52 is added, on the home screen 40. In this example, since 10 icons 50 can be additionally contained in the folder 52, a numeral “10” is included in the image 53.
By the control illustrated in FIG. 7, the number of icons containable in the folder 52 disposed on the home screen 40 can be comprehensibly displayed to the user.
FIG. 8 represents an example of control for displaying that the number of icons contained in a folder reaches an upper limit number containable.
At Step S31, 11 icons are contained in a folder 52. Accordingly, a numeral “11” is included in an image 53 added to the folder 52. As illustrated in Step S31, for example, when an icon 50c is long-touched with a finger of the user, the smartphone 1 detects the same as a movement start operation for the icon 50c. 
Subsequently, as illustrated in Step S32, when the icon 50c is dragged by a finger of the user and is superimposed on the folder 52, the smartphone 1 contains the icon 50c in the folder 52.
Subsequently, as illustrated in Step S33, since the number of icons contained in the folder 52 reaches an upper limit number containable “12” as a result of containing the icon 50c in the folder 52, the smartphone 1 changes the image 53 added to the folder 52, to indicate that the number of contained icons reaches the upper limit number containable. In this example, the image 53 includes “F” indicating that the number of contained icons reaches the upper limit number containable.
By the control illustrated in FIG. 8, the fact that the number of icons contained in the folder 52 disposed on the home screen 40 reaches the upper limit number containable can be comprehensibly displayed to the user. A mode for displaying that the number of icons contained in the folder reaches the upper limit number containable is not limited to the example illustrated in FIG. 8. For example, the smartphone 1 may include another numeral, character, or symbol, which indicates that the number of contained icons reaches the upper limit number containable, in the image 53. Alternatively, when the number of contained icons reaches the upper limit number containable, the smartphone 1 may perform a display mode change, such as a color change or blinking, on the image 53.
The display of the number of icons contained in the folder may not always be performed. For example, the smartphone 1 may display the number of icons contained in the folder, in response to the detection of an operation for moving an icon. FIG. 9 represents an example of control for displaying the number of icons contained in a folder, in response to the detection of a movement start operation for an icon.
At Step S41, for example, a plurality of icons including an icon 50d, and a folder 52 containing a plurality of icons are disposed on the home screen 40. It is assumed that two icons are currently contained in the folder 52. Subsequently, as illustrated in Step S42, for example, when an icon 50d is long-touched with a finger of the user, the smartphone 1 detects the same as a movement start operation for the icon 50d. In response to the detection of the movement start operation for the icon 50d, the smartphone 1 adds an image 53 indicating the number of icons contained in the folder 52, to the folder 52.
By the control illustrated in FIG. 9, since the number of icons contained in the folder 52 is displayed at the time of using the folder 52, the number of contained icons can be comprehensibly displayed to the user, while reducing the burden of always displaying the number of contained icons.
FIG. 10 represents an example of control for displaying the number of icons containable in a folder, in response to the detection of a movement start operation for an icon.
At Step S51, for example, a plurality of icons including an icon 50d, and a folder 52 containing a plurality of icons are disposed on the home screen 40.

Subsequently, as illustrated in Step S52, for example, when an icon 50d is long-touched with a finger of the user, the smartphone 1 detects the same as a movement start operation for the icon 50d. In response to the detection of the movement start operation for the icon 50d, the smartphone 1 adds an image 53 indicating the number of icons containable in the folder 52, to the folder 52.
By the control illustrated in FIG. 10, since the number of icons containable in the folder 52 is displayed at the time of using the folder 52, the number of contained icons can be comprehensibly displayed to the user, while reducing the burden of always displaying the number of contained icons.
FIG. 11 represents an example of control for displaying that the number of icons contained in a folder reaches an upper limit number containable, in response to the detection of a movement start operation for an icon.
At Step S61, for example, a plurality of icons including an icon 50e, and a folder 52 containing a plurality of icons are disposed on the home screen 40. It is assumed that 12 icons are currently contained in the folder 52. Subsequently, as illustrated in Step S62, for example, when an icon 50e is long-touched with a finger of the user, the smartphone 1 detects the same as a movement start operation for the icon 50e. In response to the detection of the movement start operation for the icon 50e, the smartphone 1 adds an image 53 indicating that the number of contained icons reaches the upper limit number containable, to the folder 52.
By the control illustrated in FIG. 11, since that the number of icons contained in the folder 52 reaches the upper limit number containable is displayed at the time of using the folder 52, the fact that the number of contained icons reaches the upper limit number containable can be comprehensibly displayed to the user, while reducing the burden of always displaying that the number of contained icons reaches the upper limit number containable. Although FIGS. 9 to 11 illustrate the examples of adding the image indicating the containing status of the folder to the folder in response to the movement start operation for the icon, the condition for adding the image indicating the containing status of the folder to the folder is not limited thereto. For example, the smartphone 1 may add the image indicating the containing status of the folder to the folder in response to the detection of a drag operation of the icon 50.
